Hello Johanna, I am using scimax from John Kitchin [[https://github.com/jkitchin/scimax ]]and I recommend it to you warmly.
In my /user/user.el, here is what is about beamer : #+BEGIN_SRC lisp (add-to-list 'org-latex-classes '("beamer-ahp-ul" "\\documentclass\[10pt,svgnames,fragile]\{beamer\} [NO-DEFAULT-PACKAGES] [PACKAGES] [NO-EXTRA] \\theoremstyle{plain}% default \\newtheorem{thm}{Theorem}[section] \\newtheorem{theo}{Théorème}[section] \\newtheorem{lem}[thm]{Lemma} \\newtheorem{prop}[thm]{Proposition} \\newtheorem*{cor}{Corollary} \\theoremstyle{definition} \\newtheorem{defi}{Definition}[section] \\newtheorem{rema}[thm]{Remarque} \\newtheorem{Conjecture}[theorem]{Conjecture} \\newtheorem{exa}{Example}[section] \\newtheorem{exem}{Exemple}[section] \\\hypersetup{colorlinks, citecolor=blue, linkcolor=., menucolor=white, filecolor=pink, anchorcolor=yellow } \\AtBeginSection\[\]\{\\begin\{frame\}<beamer>\\frametitle\{\}\\tableofcontents\[currentsection,hideothersubsections\]\\end\{frame\}\} \\subtitle\{\} \\institute\[Université de Lorraine\]\{Département de philosophie \\\\ Archives Henri Poincaré - UMR 7117 du CNRS \\\\ Université de Lorraine \\\\ 91 bd Libération, 54000 Nancy \\\\ France \} \\titlegraphic\{\\includegraphics\[height=1cm\]\{ahp\}\\includegraphics\[height=1cm\]\{udl\}\\includegraphics\[height=1cm\]\{cnrs\}\} \\usetheme\{CambridgeUS\} \\usepackage\{beamer_udl_theme\} \\setbeamertemplate\{navigation symbols\}{% %insertslidenavigationsymbol% %insertframenavigationsymbol% %insertsubsectionnavigationsymbol% %insertsectionnavigationsymbol% %insertdocnavigationsymbol% %insertbackfindforwardnavigationsymbol% } \\setbeamertemplate{theorems}[numbered] " ("\\section\{%s\}" .

I have nothing with notes, but I hope it helps. Best wishes, Jo.
